Application tiled Illcceniher ll, 191?. lierial lilo. sconce To all whom it may concern Be it known that I, GEORGE ll. liinsnnn, a citizen of the United States residing at Hartford, in the county of Hartford and State of Connecticut, have inventedcertain new and useful Improvements in Universal Joints, of which the following is a specilication.

This invention relates to universal joints. lit is more or less common. in an article of this character to provide a dust-guard com prising a cup which generally encircles one of the elements of the joint and which bears against the other. lit is usual to hold this cup member in its operative position by spring means. One of the fundamental pur poses l have in view is the provision of an abutment for the spring means which can be easily mounted in place and which can he held in active relation without the necessity oi separate l astenings', thus insuring ccononly and as an incident readiness and ease of assemblage.

In the drawings accompanying and fornn ing part of the present specification I have shown in detail a form of embodiment of the invention which I will set :l'orth fully in the following description to enable those skilled in the art to practice the invention.

1'. am not restricted, however, to this pan ticular showing; I may depart therefrom in severalrespects within the scope oi? the invention defined by the claims following said description;

Referringto said drawings: l igure l is an elevation of the joint.

Fig. 2 is a practically similar VlElW with a portion broken away and in section.

Fig. 3 is a transverse section on the line 3'3 of Fig. 2, looking in the direction of the arrows.

Fig.4; is a perspective view of a portion of the abutment shown in the other views.

Like characters refer to li he carts throu lr out the several. figures which it will be per" ccived, are on different scales.

The device comprises in its make-up two members such as those denoted in a general way by 2 and 3. These members are con nected for relative universal IHUVEIYIGHE. The part 2 hasassociatedwith it a dust- ;zuard comprising; the cup ncn'iloer "l of prim tically spherical shape. The member 3 is equipped with a stem or shank around which the reduced portion of the cup meni- -inner forward side wit her 4-. fits. The latter contains a inching ring 6 which hugs the member 2. Thisin fact isa concise description of a commontype of universal joint with which my improve ment can operate with advantage. As will so be evident, this improvement can he used with utility'in conj unction with other forms of joints.

The cup member l is yieldingly held in its advanced relation to maintain the packing 6 atall times in proper contact with the practically spherical portion of the member 2 in some convenient way, the coiled spring 7 encircling the stem or shank 5, heing shown for this purpose. The invention, as "to will be obvious, resides in the abutment for this spring or its equivalent. The abutment for the spring is denoted in a general way by 8 and shown is in the form of alsp'lit* ring surrounding the stern or shank 5 and are associated therewith in a novelniainner.

. This abutment'or ring as shown is made up of two duplicate sections 9 and 10 Wholly separate from each other, in view of which circumstance the parts 9 and 10 can he septo arately mounted or dismounted. Each of the sections 9 and 10 is rovided along its a semi-annular flange or head 11. In addition to this the same is provided with an outwardly extending head or flange 12 along its rear side. The stem or shank 5 as shown has between its ends the circular channel or groove 13 which constitutes a seat for-the divided ri g or collar 8, the groove or channel heingof so a depth to properly receive the two flanges 11, When the parts of the ring 8 are-in assembled relation with the stem or shank 5 as shown for illustration by Fig. 3, the

ends of the sections of the ring are spaced or separated from each other a coniparatively small distance. The two flanges 1O mate to present a stop to receive the outer end of the spring 7 as shown for illustration by both Figs. 1. and 2. At this time as will we he clear, the front portion of the spring hugs the neck part oi the cup member 4 and acts against the cup member to hold it advanced and in yielding engagement with the joint member 93. abutment or divided ring 8 is not in the ctr-- din ary sense hastened to the hearing; member 3 of which the shank 5 forms a part.

lit becomes a simple matter to opcratively associate the several elements.

lit will be clear that the lit will he llu assumed that the arts 2 and 3 of the joint are assembled an that the cup member i is applied. In this event the coiled spring 7 Will be passed over the stem or shank 5 and the spring condensed or compacted from its outer end sufiicieutly to permit the pand to engage against the flanges 100i split or divided ring, these flanges 10 as will be clear, constituting an ample bearing for the spring.

,It will be clear that the universal joint comprises two members, a cup to bear against one of the members, a spring acting against the cup, and an abutment for the spring, the other member having a bearing for the abutment, the spring acting to hold the abutment against its bearin In view out this condition, it is of course, unnecessary to provide any independent or extraneous means to hold the ring or its equivalent in. position. The ring acts as an effective abutment for the spring and the spring holds the abutment in position a ainst accidental movement or withdrawa What I claim is: v

1. A universal joint comprising two bore, a cup to bear against one ofthe bers,'a spring acting against the cup, and an abutment for the spring, the other meniher having a bearing for the abutment, the spring acting as the sole means hold the abutment against its bearing.

2. A universal joint comprising two members, a cup bearing against one of the members, aspring acting against the cup, and a multi-part ring, the other member being grooved to receive the parts of thering and and the spring" mesmethe ring being engaged by the spring, the spring holding the parts of the ring in the groove and the ring acting in turn as an abutment for the sprin -2 a 3. A universal joint comprising two meinbars, a cup bearing against one of the membars, a spring acting against the cup, and a and the sections of the ring being flanged to fit the groove, the ring having external means tobe engaged by the spring and the spring holding the flanges of the sections of the ring in said groove.

\ 5. A universal joint comprising two members, a cup bearing a ainst one of the members, the other menu or having a stem, a coi ed spring surrounding the stem and bearing against the cup, and a multi-part ring around the stem, the latter having a groove and the sections of the ring being flanged on their inner sides to fit the groove, the secoi the ring having external flanges to be engaged. by the outer end of the sprin holding the inner flanges o. the sections 02. the ring in said groove.

In testimony whereof I afiix my signature in the presence or two witnesses.
